I got the same vibe from Galactic Civilizations II. I'd generally convert enemy territories with what was basically culture in that game, though. Bribe enemies to war each other, subvert newly conquered territories to my side, give advanced technology to the enemies of any nation that wised up to what I was doing... priceless. :D
